Application July 23',1934., serial N 736,596 13 Claims: (01. 199-41 lvIy invention relatesgenerally to linotype machines, and particularly to means for handling,-sorting, and selecting matrices entirely by machine, and an importantobject of the invention is to provide a device of the characterindicated wherein any desired number of different matrix feedingmagazines may be used so as to eliminate entirely the necessity forchanging magazines to accommodate diiierent kinds and sizes of type.

Another important object of my inventionis to provide a device of thecharacter indicated which will pick up the used matrices from the moldand automatically sort the matrices of different size and form intocorresponding individual magazines, from which the matrices may beselectively fed back to the mold through operation of an electrical gatesystem controlled by a keyboard, the entire cycle being automatic andcontinuous if desired.

It will be understood as a condition precedent 20 to a properunderstanding of the following description that the molding with thematrices, the removal of the matrices from the mold. and theapplicationof the matrices to the mold is carried on by conventionalmeans and in the or- 25 dinary manner, the functioning of the apparatusof the invention occupying the sphere which is interposed between thetaking of the matrices from themold after the casting, and the delivcryof the selected matrices to the belt conveyor 30 for delivery to thecomposing device.

Referring in detail to the drawings, the numera1 lil refers generally tothe pusher device which operates to push onto and along the primarydistributing or selector bar ll the matrices l2 for 35 selectivedelivery into the individual chutes l through 8, inclusive. The bank ofchutes l th f l lifi' is placed under the delivery portion l3 of theprimary distributor bar with the funnel upper ends thereof placed inline along and 40 beneath the portion l3 as shown in Figure 2.

The. form of'the portion l3 of the selector. bar II is shown in Figure5. The inner sides of-the depending wings l5, l5 are provided withdownwardly angulated teeth as indicated at is, ii to engage theoppositely formed teeth l8, E9 on the upper part of the matrix jIZ. Theinverted V- shaped spine 29 which is located between the portions M, i5is smooth so as to fail to engage the right an'gularly arranged teeth 25in the top notchof the matrix. Shoulders 22, 23 are arranged ontheopposite edges of the matrix just below the. teeth portions [8, I9 soas to rest on the shoulders 24. Asjthe matrices are pushed along thebarv H by the pusher Hi, the matrices having different arrangements ofthe shoulders 22, 23, and different arrangements of the teeth I8, l9,will in meeting different formations of the teeth l6, ll on the interiorof the portion I 3 and different formations of the shoulders 24, becaused to drop from the portion l3 into the upper end of the properchute. Although for illustrative purposes a bank of eight chutes andeight magazines have been shown, it will be understood that any desirednumber of chutes and corresponding magazines may be provided.

Below the funnel tops of the chutes I through 8 the chutes areadequately reduced in size as indicated at 25 to properly convey thematrices in the erect position to their lower ends. The lower end ofeach chute is closed as indicated at 25 and has front and backopenings21 and 28 permitting the matrices to come into contact with the left andright hand screws 29,, 30', respectively, which project through theopenings 21 and 28 as shown in Figure 5. A third screw 3| having accessto the interior of the lower end of the chute below the. screw 29through the opening 32 in the chute is in cooperation with the screws29, 3D to hold the matrix properly erect and to push the same up theramps 33, 34 which properly elevate the matrices so as to engage withthe corresponding secondary distributing bar 35 which leads to thecorresponding one of the magazines 8, I, 5', 5', 4, 3', 2 and I, asindicated in Figure 4.

As the matrices drop through the chute, the lowermost one is stopped byengagement of one of each of the shoulders with the arm 36 of the latchgenerally designated 31 which consists of the J-shaped bar 38 which ispivoted on a suitable support as indicated at 39 and has the shorter arm40 which like the arm 36 passes through an opening in the back of thepart 25 of the chute. When the latch 38 is swung toward the left inFigure 5 the arm 36 will be withdrawn from the lower end of the matrixand permit the matrix to fall to the position in which the lowermostmatrix is shown in Figure 5, while the arm 40 engages between thevertically spaced shoulders on the next above matrix momentarily andthen is withdrawn. As the latch 38, with the matrices positioned asshown in Figure 5 is swung toward the right, the arm 36 will bewithdrawn from supporting relation to the lowermost matrix and permitthe lowermost matrix to fall into the bottom 26 of the chute and intoengagement with the screws 29, 30 and 3|, so that the shoulders of thematrix engage in the grooves of the screws and move toward the right, upover the ramps 33, 34 and on to the secondary distributing bar. Thescrew 29 has outwardly, that is to the left of the portion 4| of thechute 8., the cam 42 which is in operative relation with a leg 43 of thelatch 38, so as to operate the latch 38 in the manner already indicatedat exactly spaced times, so as to effect controlled and intermittentfeeding of the matrices 12 into engagement with the screws for transferto the magazine 8'. The screws are driven by a conventional arrangementalready known in the art,- although presently used only with deviceshaving two or four magazines only. Since each of the chutes of themechanism is similar to the one just described, it is believed that thedescription of each of the individual mechanisms is unnecessary.

It will be observed that the underside of the distributor bar 35 isV-shaped and provided with teeth 44 which have a flat horizontalundersurface adapted to engage with the teeth I8, l9 of the matriceswhich have angulated lower surfaces. It will also be observed thatcertain portions of the teeth 44 on the bar 35 terminate at selectedpoints as indicated at 45, 46, 41, 48, and so on which discontinue in amanner to permit certain ones of the matrices to drop from the bar 35 inposition to exactly enter one of the compartments 49 of the magazine 8',each of the compartments 49 corresponding to one of the letters of thealphabet or with one of the punctuation marks, or other marks or signs,according to the arrangement desired.

It will be understood that throughout the present description that eachof the matrices is differentiated from the other not only by thearrangement of its shoulders and teeth but also by v the arrangement ofits teeth in the top notch thereof, so that the main distributing barand the secondary distributing bars can only support any given matrixuntil a point in the travel of the matrix thereon is reached whence thematrix should fall from the corresponding distributor bar into thecorresponding chute or compartment of one of the magazines.

Reference to Figures 3 and 13 in conjunction with Figure 1 will give aproper idea of the construction and arrangement of the magazines andtheir relation to the chutes I, 2, 3', 4, 5', 6', 1 and 8', and thesecondary distributing bars which deliver the matrices to the magazines.

Each magazine comprises a longitudinally elongated hollow member whichis divided as indicated in Figure 4 into a multiplicity of compartments49, and the magazines have a downward and forward inclination asindicated in Figure 1, terminating at their lower ends in the deliverychutes generally designated 45 which empty onto the conveyor belt 46which for convenience may be located above and to the rear of thekeyboard which is generally designated 41.

Each compartment of each magazine has at the lower end thereof an arm 48which is pivoted near its lower end as indicated at 49 to a suitablesupport and has on opposite sides of the pivot the long arm 50 and theshort arm 5| which are slidable through openings in the lower side ofthe compartment as shown in Figure 3. The lower end of the arm 49 has aweight 52 heavy enough to act as a counter-balance for the extendedportion 53 which is in the form of an armature for operation by anelectro-magnet 54 located on the underside of the magazine near theupper end thereof as shown in Figure 1. When the extended portion 53 ofthe arm 48 is attracted and moved upwardly by its electromagnet 54 thearm 5! will be pushed into the compartment 49 into a position betweenthe shoulders of the adjacent matrix, while the arm 50 will be withdrawnfrom engagement with the upper shoulder of the adjacent matrix so as topermit the lowermost matrix in the compartment 49 to slide and fall intothe curved portion 55 of the upper end of the delivery chute 45. Whenthe magnet 54 is deenergized the weight 52 will not effect the return ofthe extended portion 53 to the depressed position shown in Figure l, butwill prevent the portion 53 from dropping too far, as will engagement ofthe arm 50 with an adjacent matrix. It will be obvious that themomentary swinging of the arm 48 accompanied by its return to initialposition will effect intermittent delivery of matrices in thecompartment 49 into the upper end of the chute 45.

In order to prevent the matrices which'fail through theupper parteofthe'chute'45 from catching in the openingof the'next lower neck 56 whichis fed by another compartment 49 equipped with a similar gate mechanism,I provide the swinging gate 57 which is pivoted. at its'upper end asindicated at 58 to'the top of the last-mew tioned opening, so as tomaintain the width "of the passage in the chute unbroken to guide-thefalling matrices. The lower end of the gate 5? engages the lower part ofthe last-mentioned opening so as to resist movement by the matrices. asthey fall through the chute. However, matrices passing through the neck56 move the gate 51 out of the way by swinging the gatev toward thefront of the chute. Two of the gates 51 are shown in front elevation inFigure 13. The front of the chute is equipped with a glass windowthrough which the operator of the keyboard may View the dropping of thematrices selected by him. r

The keyboard generally designated il contains magazine keys 60 which arepivoted as indicated at B2 and have their rear ends under plungers 63having a contact 6 3 engageable when pushed upwardly with the contact65, the plunger and the contact being mounted in a suitable'block 66, sothat when the key 69 is depressed the corresponding magazine switch willbe closed to energize the electro-magnet corresponding thereto. Thenumeral 68 is used to designate not only the magazine selecting key oftheswitch board but the switch as a whole which. is operative uponpressing the key 66, while the letter selecting keys are each similarlydesignated El and regarded as a whole as a switch, especially in thedesignation of the features of the wiring diagram in Figure 9.

Inoperating the device of the invention the magazine selecting key 68 ispressed which corresponds to the magazinecontaining the kind or size ofletters or signs chosen, and then the letter selecting key 6| is pressedfor the purpose of selecting the desired letter from the selectedmagazine. The effect of closing. the switch 66] and then the letterselecting switch 8! is to energize the electro-magnet 54 correspondingto theselected oneof the magazine, and particularly the electro-magnet54 corresponding to the compartments 49 of the selected magazine whichcontain the matrices having thereon the letters chosen; so that therespective gate mechanisms already described and shown in Figure 3 willbe operated so as to release from the specified compartments of theselected magazine, the desired matrices which then fall through thedelivery chute 15 onto the conveyor belt tii and are moved by the beltto the composition block and then to the mold or casting; followed byremoval from the mold and return to the magazines. Although I have shownand described herein a preferred embodiment of my invention, it is to bedefinitely understood that I do not desire to limit the application ofthe invention thereto; and any change or changes may be made inmaterials, and in the structure and arrangement of parts, within thespirit of the invention and the scope of the subjoin-ed claims. 1
